Aphasia -disorder caused by damage to the brain


Aphasia is a disorder caused by damage to the parts of the brain that control language. It can make it hard for you to read, write and say what you mean to say. It is most common in adults who have had a stroke. Brain tumors, infections, injuries and dementia can also cause it. The type of problem you have and how bad it is depends on which part of your brain is damaged and how much damage there is.

There are four main types:

  • Expressive aphasia – you know what you want to say, but you have trouble saying or writing what you mean
  • Receptive aphasia – you hear the voice or see the print, but you can’t make sense of the words
  • Anomic aphasia – you have trouble using the correct word for objects, places or events
  • Global aphasia – you can’t speak, understand speech, read or write

Some people recover from aphasia without treatment. Most, however, need language therapy as soon as possible.

Communicating with someone with aphasia

People with have aphasia have speech problems. They may have trouble:

  • Finding the right word
  • Saying more than 1 word or phrase at a time
  • Speaking at all

This type of aphasia is called non-fluent aphasia. People who have it may understand what another person is saying to them, or they may NOT understand or be able to speak.

Another kind of aphasia is fluent aphasia. People who have fluent aphasia may be able to put many words together, but what they say may not make sense. They are often unaware that they are not making sense.

People who have either kind of aphasia may become frustrated when they realize others cannot understand them, when they cannot understand others, or when they cannot find the right words.

A speech and language therapist can work with a person who has aphasia and their family or caregivers to improve their ability to communicate.

The most common cause of aphasia is a stroke. Recovery may take up to 2 years, though not everyone fully recovers.

Improving Daily Communication

There are many ways to help a person with aphasia.

Keep distractions and noise down:

  • Turn off the radio and TV.
  • Move to a quieter room.

Talk to people who have aphasia in adult language. Do not make them feel as if they are a child. Do not pretend to understand them if you do not.

If they can not understand you, do not shout. Unless they also have a hearing problem, shouting will not help. Make eye contact when talking to the person with aphasia.

When you ask questions:

  • Ask questions in a way they can answer you with a simple “yes” or “no.”
  • When possible, give clear choices for possible answers, but do not give them too many choices.
  • Visual prompts are also helpful, when you can give them.

When you give instructions:

  • Break down instructions into small and simple steps.
  • Allow time for the person with aphasia to understand. Sometimes this can be a lot longer than you expect.
  • If the patient becomes frustrated, consider changing to another activity.

You can encourage the person with aphasia to use other ways to communicate. Some are:

  • Pointing
  • Hand gestures
  • Drawings

It may help the person with aphasia and their caregivers to make a book with pictures or words about common topics or people so that they can communicate better.

Always try to keep the person with aphasia involved in conversations. Check with them to make sure they understand. But do not push too hard for them to understand, since this may cause more frustration.

Do not try to correct the person with aphasia if they remember something incorrectly.

Begin to take the person with aphasia out more, as they become more confident. This will allow them to practice communicating and understanding in real-life situations.

When leaving someone with speech problems alone, make sure they have an ID card that:

  • Has information on how to contact family members or caregivers
  • Explains their speech problem and how best to communicate with them
